[SOLVED] AppWall GUI Crash

[david.garcia]

Hi,

 

We have an AppWall 3x1 and when we are trying to insert a WidgetSprite in each wall application crashes with the following message:

 

 engine\render\direct3d11\framework\D3D11Gui.cpp:166: Assertion: 'src >= 0 && src < NUM_BLEND_FUNC && "D3D11Gui::set_blend_func(): bad blend src function"'

 

You can reproduce this issue creating a new project from Ungine SDK browser with the following settings:

 

- Launchers:

 

Console script launchers (.bat) with predefined settings

 

Renderer: DirectX11

Monitors: Wall 2x1

 

- Video Output

 

Monitor wall (AppWall plugin) CHECKED

 

 

After this step in the "my_project".cpp file, you have to change the init method to this:

 

int init() {

    PlayerSpectator camera = new PlayerSpectator();

    camera.setPosition(Vec3(2.0f,0.0f,1.5f));

    camera.setDirection(Vec3(-1.0f,0.0f,-0.5f));

    engine.game.setPlayer(camera);

 

 

    forloop(int y = 0; engine.wall.getHeight()) {

        forloop(int x = 0; engine.wall.getWidth()) {

            Gui gui = engine.wall.getGui(x,y);

            WidgetSprite logo = new WidgetSprite(engine.getGui(), "unigine.png"); 

            gui.addChild(logo,GUI_ALIGN_OVERLAP);

        }

    }

 

    return 1;

}

 

What's wrong?

 

 

Thanks in advance,

Hi David,

 

Thank you for the detailed description! Could you please provide additional information about this issue:

• How many monitors are connected to the PC?
• What OS and Unigine SDK version are you currently using?
• What is the value of video_fullscreen variable in your launch options?
• Can you reproduce this issue with only one monitor connected?
• Can you reproduce this issue after deleting my_project/unigine.cfg file?

Thanks!

Hi Silent,

• How many monitors are connected to the PC? -> 2
• What OS and Unigine SDK version are you currently using? -> Windows; UNIGINE_Sim_source_windows_2014-03-25
• What is the value of video_fullscreen variable in your launch options? -> 0
• Can you reproduce this issue with only one monitor connected? -> I can reproduce this issue.
• Can you reproduce this issue after deleting my_project/unigine.cfg file? -> I can´t reproduce

The differences between config files are:

 

Before delete:

 

<item name="show_gpu" type="int">1</item>

<item name="video_mode" type="int">13</item>

<item name="video_resizable" type="int">1</item>

 

After delete:

 

<item name="video_mode" type="int">-1</item>

<item name="video_resizable" type="int">0</item>

 

Thanks!

Hi Silent,

I've modified the appWall plugin to solve this problem. If you disable the render_gui method on the startup the application don't crash.

Thanks
